#### 1.2 数据模型
```kotlin
// data/model/User.kt
data class User(
    val id: String,
    val phone: String,
    val name: String,
    val token: String,
    val avatarUrl: String? = null

interface AuthApi {
    @POST("auth/send-code")
    suspend fun sendVerificationCode(@Body phone: Map<String, String>): Response<Unit>

    @POST("auth/login")

                instance
            }
        }
    }
}
```

#### 1.5 Repository层
```kotlin
// data/repository/AuthRepository.kt
class AuthRepository @Inject constructor(
    private val authApi: AuthApi,
    private val userDao: UserDao,
    private val prefs: SharedPreferences

                        userDao.insertUser(userEntity)
                        // 保存token到SharedPreferences
                        prefs.edit().putString("auth_token", loginResponse.token).apply()
                        Result.success(loginResponse.user)

                    }
                } ?: Result.failure(Exception("响应数据为空"))
            } else {
                Result.failure(Exception("网络请求失败"))
            }
        } catch (e: Exception) {
            Result.failure(e)
        }
    }

    suspend fun getCurrentUser(): User? {

    }

    suspend fun logout() {
        prefs.edit().remove("auth_token").apply()
        userDao.clearAllUsers()
    }
}
```

#### 1.6 ViewModel
```kotlin

    private val _uiState = MutableStateFlow(LoginUiState())
    val uiState: StateFlow<LoginUiState> = _uiState.asStateFlow()

    private val _uiEvent = Channel<LoginUiEvent>()
    val uiEvent: Flow<LoginUiEvent> = _uiEvent.receiveAsFlow()

    fun sendVerificationCode(phone: String) {
        viewModelScope.launch {
            _uiState.update { it.copy(isLoading = true) }
            authRepository.sendVerificationCode(phone)

                }
        }
    }

    fun login(phone: String, code: String) {
        viewModelScope.launch {
            _uiState.update { it.copy(isLoading = true) }

                }
        }
    }
}

// ui/login/LoginUiState.kt
data class LoginUiState(
    val isLoading: Boolean = false,
    val isCodeSent: Boolean = false,
    val phone: String = "",

sealed class LoginUiEvent {
    data class ShowError(val message: String) : LoginUiEvent()

```

#### 1.7 UI实现
```kotlin

#### 2.2 权限管理
```kotlin
// utils/PermissionManager.kt
class PermissionManager @Inject constructor(
    @ApplicationContext private val context: Context
) {

    fun hasCameraPermission(): Boolean {
        return ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA) ==
            PackageManager.PERMISSION_GRANTED
    }

    fun hasAudioPermission(): Boolean {
        return ContextCompat.checkSelfPermission(context, Manifest.permission.RECORD_AUDIO) ==
            PackageManager.PERMISSION_GRANTED
    }

    fun getRequiredPermissions(): Array<String> {
        return arrayOf(
            Manifest.permission.CAMERA,
            Manifest.permission.RECORD_AUDIO
        )
    }
}
```

                onToggleCamera = { cameraToggled = true },
                onToggleMicrophone = { microphoneToggled = true },
                onSwitchCamera = {},
                onBackPressed = {}

        // 点击摄像头按钮
        composeTestRule.onNodeWithTag("camera_button").performClick()
        assertTrue(cameraToggled)

        // 点击麦克风按钮
